MAC Ultra Wash Safety and Installation Manual
Physical installation
Installation safety
The fixture weighs 39 kg (86 lbs.), not including installation hardware.
See “Dimensions” on page 2 for details of the fixture’s physical dimensions.
Warning! The MAC Ultra Wash has a powerful pan motor. The torque reaction when the head is
panned suddenly can cause the base to move if the fixture is standing unsecured on a surface. Do
not apply power to the MAC Ultra Wash unless the base is securely fastened to a stable surface or
structure.
Warning! Use two evenly spaced rigging clamps to rig the fixture. Do not hang the fixture from only
one clamp. Lock omega brackets to the base of the fixture with both 1/4-turn fasteners. Fasteners
are locked only when turned a full 90° clockwise.
Warning! When suspending the fixture above ground level, secure it against failure of primary
attachments by attaching a safety cable that is approved as a safety attachment for the weight of the
fixture to the attachment point in the base. Do not use the carrying handles for secondary
attachment.
Warning! When clamping the fixture to a truss or other structure at any other angle than with the
yoke hanging vertically downwards, use two clamps of half-coupler type. Do not use any type of
clamp that does not completely encircle the structure when fastened.
Warning! To avoid head collisions when installing MAC Ultra Wash fixtures beside each other, allow
a minimum center-to-center distance between fixtures of 810 mm (32 in.). The fixture also contains a
programmable pan/tilt limitation system that allows you to limit head movement where necessary in
order to prevent head collisions. See the MAC Ultra Wash User Guide for details.
Warning! You can fasten the fixture to a surface with ratchet straps passed through the carrying
handles in the base so that the fixture cannot fall over, but do not over-tighten the ratchet straps or
you may damage the carrying handles and leave the fixture in an unsafe condition.
Warning! See Figure 2. The MAC Ultra Wash’s lens can focus sunlight and strong artificial light,
creating a potential fire hazard and causing damage that is not covered by the product warranty.
Position or shade the head so that the front lens will not be exposed to sunlight or another strong
light source from any angle – even for a few seconds.
Important! Do not point the output from other lighting fixtures at the MAC Ultra Wash, as powerful
light can damage the display.
Installation options
The MAC Ultra Wash can be fastened to a surface such as a stage or clamped to a truss in any orientation
using two omega brackets (see Figure 4) and rigging clamps. Clamps must be half-coupler type (see Figure
4) or equivalent type that fully encircles the truss unless the fixture is installed with the yoke hanging
vertically downwards, in which case other clamp types that are approved for the supported weight may be
used.
